改良加长法及口轮匝肌功能性复位修复双侧唇裂15例临床体会

Modified extension method and the orbicularis oris muscle function reduction in the repair of bilateral cleft lip: report of 15 cases

目的：探讨改良加长法及口轮匝肌功能性复位修复双侧唇裂的手术方式和临床效果。方法对2012－11-2013－10该院收治的15例双侧唇裂婴幼儿患者，采用改良加长法及口轮匝肌功能性复位进行手术修复。该方法利用侧唇上唇弓缘及极少量白唇，再造唇弓，同时对口轮匝肌进行解剖学重建。结果15例双侧唇裂患儿术后均Ⅰ期愈合，双侧唇高、鼻翼和唇红形态对称，唇弓形态良好，上唇运动时各部分协调一致，效果满意。结论双侧唇裂行改良加长法及口轮匝肌功能性复位修复术，可获得满意的外形及功能效果，值得临床推广运用。

Objective To explore the operative methods and clinical effect for bilateral cleft lip with modi-fied extension method and the orbicularis oris muscle function reduction .Methods Fifteen infants with bilateral cleft lip were treated by modified extension method and the orbicularis oris muscle function reduction treatment from No -vember 2012 to October 2013.In the method, upper lip′s arch edge of lateral lip and a small amount of white lip were used for reengineering labial arch , and the the orbicularis oris muscle was reconstructed .Results In fifteen in-fants with bilateral cleft lip primary healing was obtained , with symmetry bilateral lip height , pinna nasi , red lip and better morphology of labial arch .All parts of upper lip could coordinate when the orbicular muscles moved .The effects were satisfactory .Conclusion The patients can get excellent nasolabial profile and function through modified extension method and the orbicularis oris muscle function reduction , and this method is worthy to be popularized and applied.
